openings 5 is thus bordered on all sides by vertical flanges or walls constituting means for supporting the glass prisms 7. Each of the latter consists of a rectangular block of glass having a plane upper face and beveled side edges, and which is provided between its To all whom it may concern:

Be it known that I, WALTER HOWARD OBnrnn, a citizen of the United States, residing at Bronxville, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Vault-Lights; and I do hereby declare the following upper and lower faces with a peripheral shoulder 8 to be a full, clear, and exact description of the invenl adapted to rest upon said supporting means, the lower tion, such as will enable others skilled in the art to reduced portion 9 of each prism projecting into the which it appertains to make and use the same. opening or well bordered by said supporting means and My invention relates to a novel construction in a sideserving to maintain said prism centered in the latter. walk or vault light, the object being to provide a de- To complete the structure, the recesses between the vice of this character which is very simple, eflicient, rows of prisms and surrounding the same, are filled cheap and capable of carrying heavy loads Without apwith a suitable cement or concrete 10, which when set preciably yielding, and consists in the features of conwill obviously hold said prisms firmly in place and struction and combinations of parts hereinafter fully render the structure very inflexible. The structure described and claimed. may be further reinforced by passing rods 11 through In the accompanying drawings illustrating my inthe flanges 2 at the ends of the same and which extend vention: Figure 1 is a top plan view of a vault light parallel with and lie within the channels of said chanconstructed in accordancewith my invention. Fig. 2 is nel bars.

In Figs. 4, 5 and 6, I have illustrated a modified form a transverse section of the same on the line 2 2 of Fig. 1. Fig. 3.is a longitudinal section of the same on the line 3 3 of construction in which the channel bars 16 are laid of Fig. 1. Fig. 4 is a plan view of a modified form of construction of a vault light constructed in accordance with my invention. Fig. 5 is a vertical longitudinal section of the same on the line 5 5 of Fig. 4. Fig. 6 is a detail vertical transverse section on the line 6 6 of Fig. 4. Fig. '7 is a fragmentary detail transverse section of another modified form of construction. Fig. 8 is a fragmentary perspective view illustrating another modification in construction.

In the construction of vault lights it is desirable to incorporate the greatest possible lighting or transparent area compatible with strength and rigidity. It is further desirable that the same be constructed at the least so that the outer faces of their webs lie in contact with the vertical edges of the tongues or flanges 4 and are secured in position by means of rivets passing through one of the flanges thereof and through the plate 1. The free ends of the flanges of each two adjacent channel bars 16 are thus opposed and are separated by a space of sufficient width to permit cement or asphalt to be admitted to fill said channel bars and said space and 18 is introduced after the glass prisms 17 are disposed in position over the openings 5 and rest upon the free ends of the tongues or flanges 4 and upon the upper faces of said channel bars 16.

The flanges 2 of the plate 1 are in all instances preferably of such'depth that their upper edges flush with the upper faces of the prisms, but such depth is not essential. The construction may be further modified by substituting angle irons 19 for the said channel bars 16 as shown in Fig. 7.

In Fig. 8 I have illustrated another modification in construction which consists in employing a corrugated plate 20 and also in employing channel bars 21 having corrugated flanges, said plate being adapted to stiffen the structure and being identical in other features of construction with the plate 1, particular illustration of the openings, etc. being orn'tted from Fig. 8. The corrugated flanges of the channel bars 21 are adapted to present a larger area for adhesion of the cement filling and are stiffer than plane flanges thus enabling a lighter metal to be employed in their construction.

my device comprises a base plate 1. of sheet-metal preferably of relatively heavy gage, provided on its edges with up-turned flanges 2.

In the body portion of said plate 1 I provide H- shaped incisions 3 disposed in parallel rows at regular intervals and said rows being regularly spaced. By this means I provide free tongues or flanges 4 which are bent to extend upwardly at right angles to the plane of the body and thus border two opposing edges of each of the rectangular openings 5. All of the said flanges 4 are disposed parallel wi'h each other and extending transversely thereto and abutting against the vertical edges thereof are disposed channel bars 6 having flanges of a depth equal to the depth of said tongues in flanges 4 and having the outer faces of their webs resting upon said plate 1., the outer faces of the flanges of said channel bars being disposed in contact with the opposing vertical edges of said tongues or flanges 4 of adjacent i rows. The said channel bars 6 are riveted to said plate I claim as my invention:
